When it comes to how the dinosaurs went extinct, we’ve been fed a number of theories over the years.

They died because a giant asteroid hit the Earth; they died because of catastrophic volcanic activity; they died because of climate change; they died because of shifting tectonic plates.

“Scientists have finally discovered — definitively, they say — what killed the dinosaurs 66 million years ago,” says Pat Gray.

“It’s pollen. Yeah, turns out they all died from really bad allergies.”

If you think we’re kidding — we’re not.
